Table 4.
Health outcome of reported confirmed* human VTEC cases during 2007–2010 as categorized based on the reported haemolytic uraemic syndrome (HUS) cases of human VTEC in the EU in 2007–2010 [grouped as HAS (A/B/C)]. Based on The European Surveillance System data as provided by the European Centre for Disease Prevention and Control

Confirmed cases are laboratory confirmed and may or may not fulfil the clinical criteria as described in the case definition. For the majority of these confirmed VTEC cases, the clinical outcome was not reported: the case fatality was not reported for 52% of these cases, hospitalization was not reported for 90% and HUS status was unknown for 41%. The clinical manifestation (expressed as bloody diarrhoea, diarrhoea or asymptomatic) was not reported for 47% of the cases. Percentages of cases are given within parentheses based on rows ( ) and within square brackets based on columns [ ].
HAS, HUS-associated serotypes. Includes the serotypes that have been associated with reported confirmed HUS cases of human VTEC in EU in 2007–2010: O157:H7, O157:H–, O121:H19, O26:H11, O174:H2, O111:H–, O145:H–, O145:H28, O1:H42, O128:H2, O111:H8, O104:H21, O174:H21, O7:H6, O76:H19, O80:H2, O86:H27, O121:H2, O123:H2, O105:H18, O91:H10; seropathotype D includes the serotypes that have been fully serotyped but have not been associated with the reported confirmed HUS cases of human VTEC in EU in 2007–2010; NFT, strains that were not fully serotyped.
